CoffeeScript 1.4.0 Released, No Sign of Source Maps

CoffeeScript 1.4 has arrived! There is not a whole lot to get excited about unless you're using CoffeeScript with Node.js and are tired of deprecation warnings. You can compare the new version with 1.3.3 on this GitHub compare view.

After writing about source maps for CoffeeScript back in April 2012, I felt fairly sure that the 1.4 release would usher in a new era of easier debugging for CoffeeScript. It will certainly come.

Meanwhile, the change log for 1.4.0 on the official CoffeeScript site looks like this:

The CoffeeScript compiler now strips Microsoft's UTF-8 BOM if it exists, allowing you to compile BOM-borked source files.

Fix Node/compiler deprecation warnings by removing registerExtension, and moving from path.exists to fs.exists.

Small tweaks to splat compilation, backticks, slicing, and the error for duplicate keys in object literals.
